Static variables are the variables which has exactly one copy per class. They belong to the class as a whole but not for its instances (objects). All static variables are declared by using the modifier ‘static’.
For example:
What is Polymorphism in C++?
What is Inheritance in C++?
What is the validity of template parameters? a) inside that block only b) inside the class c) whole program d) any of the mentioned
Which of the things does not require instantiation? a) functions b) non virtual member function c) member class d) all of the mentioned
Which keyword can be used in template? a) class b) typename c) both a & b d) function
What is the output of this program?
#include <iostream>
using namespace std;
template <class T, int N>
class mysequence
{
T memblock [N];
public
void setmember (int x, T value);
T getmember (int x);
};
template <class T, int N>
void mysequence<T,N> setmember (int x, T value)
{
memblock[x] = value;
}
template <class T, int N>
T mysequence<T,N> getmember (int x)
{
return memblock[x];
}
int main ()
{
mysequence <int, 5> myints;
mysequence <double, 5> myfloats;
myints.setmember (0, 100);
myfloats.setmember (3, 3.1416);
cout << myints.getmember(0) << 'n';
cout << myfloats.getmember(3) << 'n';
return 0;
}
a) 100
b) 3.1416
c) 100
3.1416
d) none of the mentionedWhat is the output of this program?
#include <iostream>
using namespace std;
template <class T>
T max (T a, T b)
{
return (a>b?ab);
}
int main ()
{
int i = 5, j = 6, k;
long l = 10, m = 5, n;
k = max(i, j);
n = max(l, m);
cout << k << endl;
cout << n << endl;
return 0;
}
a) 6
b) 6
10
c) 5
10
d) 6
5What is the output of this program?
#include <iostream>
using namespace std;
template <class type>
class Test
{
public
Test()
{
};
~Test()
{
};
type Funct1(type Var1)
{
return Var1;
}
type Funct2(type Var2)
{
return Var2;
}
};
int main()
{
Test<int> Var1;
Test<double> Var2;
cout << Var1.Funct1(200);
cout << Var2.Funct2(3.123);
return 0;
}
a) 100
b) 200
c) 3.123
d) 200 3.123Can you please explain the difference between a template class and class template?
What is meant by template parameter? a) It can be used to pass a type as argument b) It can be used to evaluate a type. c) It can of no return type d) None of the mentioned
